4. Replace the new monitoring board, and then reinstall the controller according to the above reverse steps.
Replacement of PCB board
NOTE! Take care should be taken when replacing components of the controller. Unplugging terminals optionally
may result in system shut down. Carry out the replacement sequentially according to the following procedures.
The procedures for replacing PCB are described as follows:
1. Unplug the J8 power supply terminal to power off the PCB.
2. Unplug other terminals and DI/DO cables.
3. Wrap the DI/DO cable terminals with insulating tape. To prevent short circuit, keep the disconnected terminals and
cables insulated from components of the power system and the PCB.
